Description

La présente invention concerne un procédé de copiage d'une pièce représentée par un gabarit, à l'aide d'un copieur bidimensionnel, pouvant se déplacer suivant une direction longitudinale et une direction transversale perpendiculaire à cette dernière, avec une tourelle porte-outils et un dispositif de palpage du gabarit comprenant une vanne commandant le copieur bidimensionnel et au moins une tige de palpage, ainsi qu'un dispositif de copiage d'une pièce représentée par un gabarit d'axe longitudinal, comportant un copieur bidimensionnel comprenant un chariot longitudinal pouvant se déplacer suivant la direction longitudinale et un chariot transversal pouvant se déplacer suivant une direction transversale perpendiculaire à la direction longitudinale, et comportant également un dispositif de palpage du gabarit comprenant une vanne commandant le copieur bidimensionnel ainsi qu'au moins une tige de palpage influençant cette vanne, destiné à la mise en oeuvre de ce procédé.The present invention relates to a method of copying a part represented by a template, using a two-dimensional copier, which can move in a longitudinal direction and a transverse direction perpendicular thereto, with a tool turret and a gauge feeler comprising a valve controlling the two-dimensional copier and at least one feeler rod, as well as a device for copying a workpiece represented by a gauge of longitudinal axis, comprising a two-dimensional copier comprising a longitudinal carriage move in the longitudinal direction and a transverse carriage which can move in a transverse direction perpendicular to the longitudinal direction, and also comprising a gauge feeler device comprising a valve controlling the two-dimensional copier as well as at least one feeler rod influencing this valve, intended for the implementation of this process.

On connaît des dispositifs de copiage à copieur bidimensionnel dans lesquels la tige de palpage est perpendiculaire au plan défini par les directions longitudinale et transversale, une telle tige ne pouvant palper qu'un gabarit constitué par une tôle la plus mince possible, découpée suivant le profil de la pièce à reproduire. De tels copieurs bidimensionnels offrent une gamme très étendue de possibilités quant aux profils admissibles pour le gabarit, qui peuvent être très compliqués ; mais ils présentent l'inconvénient que ce gabarit ne peut être constitué que par une tôle mince découpée suivant le profil de la pièce à reproduire, la fabrication d'un tel gabarit étant onéreuse et délicate.Two-dimensional copier copying devices are known in which the feeler rod is perpendicular to the plane defined by the longitudinal and transverse directions, such a rod being able to feel only a gauge consisting of the thinnest sheet possible, cut along the profile of the part to be reproduced. Such two-dimensional copiers offer a very wide range of possibilities as to the profiles admissible for the template, which can be very complicated; but they have the disadvantage that this template can only be constituted by a thin sheet metal cut according to the profile of the part to be reproduced, the manufacture of such a template being expensive and delicate.

On connaît également des copieurs unidimensionnels permettant de reproduire des gabarits constitués par des solides de révolution. Ces copieurs unidimensionnels ne permettent cependant pas de reproduire des gabarits présentant des gradins de sens opposés (en montée et en descente) à moins de recourir à deux copieurs de ce genre travaillant en sens opposés.One-dimensional copiers are also known which make it possible to reproduce templates formed by solids of revolution. These one-dimensional copiers do not, however, make it possible to reproduce templates having steps in opposite directions (uphill and downhill) unless two such copiers working in opposite directions are used.

La présente invention a pour but de concevoir un procédé et un dispositif de copiage, à l'aide d'un copieur bidimensionnel, qui ne présente pas les inconvénients susdits.The present invention aims to design a method and a copying device, using a two-dimensional copier, which does not have the above drawbacks.

A cet effet, le procédé de l'invention se caractérise par le fait qu'il consiste à effectuer une première passe de copiage en palpant le gabarit à l'aide du dispositif de palpage avec une première orientation de la tige de palpage dans un plan parallèle au plan défini par les directions longitudinale et transversale, à modifier l'orientation de la tige de palpage du dispositif de palpage de manière que ce dernier présente dans ce plan une tige de palpage ayant une seconde orientation différente de la première, et à effectuer une seconde passe de copiage à l'aide du dispositif de palpage avec cette seconde orientation de la tige de palpage dans ce plan parallèle au plan défini par les directions longitudinale et transversale. Ceci permet de reproduire à l'aide d'un seul copieur bidimensionnel des gabarits constitués par des solides de révolution présentant des gradins de sens opposés.To this end, the method of the invention is characterized in that it consists in carrying out a first copying pass by palpating the template with the feeler device with a first orientation of the feeler rod in a plane parallel to the plane defined by the longitudinal and transverse directions, to modify the orientation of the feeler rod of the feeler device so that the latter has in this plane a feeler rod having a second orientation different from the first, and to perform a second copying pass using the feeler device with this second orientation of the feeler rod in this plane parallel to the plane defined by the longitudinal and transverse directions. This makes it possible to reproduce, using a single two-dimensional copier, templates constituted by solids of revolution having steps of opposite directions.

Suivant l'invention, le dispositif de copiage mettant en oeuvre ce procédé se caractérisé par le fait que le dispositif de palpage comprend une barre sur laquelle la tige de palpage est agencée de manière à s'étendre sensiblement dans le plan défini par les directions longitudinale et transversale, une première liaison pivotante entre la barre et le corps de la vanne, dont l'axe de pivotement est parallèle à ce plan défini par les directions longitudinale et transversale, et un poussoir permettant à la tige de palpage d'influencer la vanne de commande, et que le dispositif de copiage comprend des moyens agencés pour modifier l'orientation de la tige de palpage par rapport à l'axe longitudinal du gabarit. Un tel dispositif de copiage permet de palper des gabarits constitués par des solides de révolution.According to the invention, the copying device implementing this method is characterized in that the feeler device comprises a bar on which the feeler rod is arranged so as to extend substantially in the plane defined by the longitudinal directions and transverse, a first pivoting connection between the bar and the valve body, the pivot axis of which is parallel to this plane defined by the longitudinal and transverse directions, and a pusher allowing the rod to pal page to influence the control valve, and that the copying device comprises means arranged to modify the orientation of the feeler rod relative to the longitudinal axis of the template. Such a copying device makes it possible to palpate templates formed by solids of revolution.

Le dispositif de copiage suivant l'invention comprend un copieur bidimensionnel servant à reproduire une pièce représentée par un gabarit 1. Ce gabarit 1 est palpé à l'aide d'un dispositif de palpage 2 qui commande le copieur bidimensionnel de manière à usiner une pièce 3 en correspondance avec le gabarit 1.The copying device according to the invention comprises a two-dimensional copier used to reproduce a part represented by a template 1. This template 1 is palpated using a feeler device 2 which controls the two-dimensional copier so as to machine a piece 3 in correspondence with the template 1.

Le copieur bidimensionnel comprend un chariot longitudinal 4 pouvant se déplacer suivant une direction longitudinale par rapport au châssis 5 de la machine portant le copieur, cette direction longitudinale étant indiquée par une flèche 6. Le chariot longitudinal 4 est déplacé à l'aide d'un premier vérin ou groupe cylindre-piston 7, s'étendant longitudinalement, dont le cylindre 8 est fixé au châssis 5 et dont le piston 9 est fixé au chariot longitudinal 4 par l'intermédiaire d'une tige 10. Un chariot transversal 11 est mobile par rapport au chariot longitudinal 4, suivant une direction transversale, indiquée par une flèche 12, perpendiculaire à la direction longitudinale. Ce chariot 11 comprend une pièce en U 13 coulissant sur une pièce 14 solidaire du chariot longitudinal. La pièce 13 est guidée en direction transversale sur la pièce 14 grâce à une glissière. Cette pièce 13 du chariot transversal 11 porte le dispositif de palpage 2 et également une tourelle porte-outils 15. Lors du palpage d'un gabarit et de l'usinage de la pièce 3, ce dispositif de palpage 2 et cette tourelle porte-outil 15 sont sensiblement immobiles par rapport à la pièce en U 13. Le déplacement du chariot transversal 11 est assuré par un vérin ou groupe cylindre-piston 16 agencé dans la pièce 13, dont le cylindre 17 est relié de manière fixe à la pièce en U 13, et dont la tige 18 du piston 19 est fixée à la pièce 14 solidaire du chariot longitudinal 4.The two-dimensional copier comprises a longitudinal carriage 4 which can move in a longitudinal direction relative to the chassis 5 of the machine carrying the copier, this longitudinal direction being indicated by an arrow 6. The longitudinal carriage 4 is moved using a first cylinder or cylinder-piston group 7, extending longitudinally, whose cylinder 8 is fixed to the chassis 5 and whose piston 9 is fixed to the long carriage tudinal 4 via a rod 10. A transverse carriage 11 is movable relative to the longitudinal carriage 4, in a transverse direction, indicated by an arrow 12, perpendicular to the longitudinal direction. This carriage 11 comprises a U-shaped part 13 sliding on a part 14 secured to the longitudinal carriage. The part 13 is guided in transverse direction on the part 14 by means of a slide. This part 13 of the transverse carriage 11 carries the feeler device 2 and also a tool-holder turret 15. When probing a template and the machining of part 3, this feeler device 2 and this tool-holder turret 15 are substantially stationary relative to the U-shaped part 13. The movement of the transverse carriage 11 is ensured by a jack or cylinder-piston group 16 arranged in the part 13, the cylinder 17 of which is fixedly connected to the U-shaped part 13, and the rod 18 of the piston 19 of which is fixed to the part 14 integral with the longitudinal carriage 4.

Suivant l'invention, le gabarit 1 utilisé avec ce copieur bidimensionnel est constitué par un solide de révolution qui est maintenu entre deux pointes 20, immobiles par rapport au châssis 5 de la machine. Le dispositif de palpage 2 comprend suivant l'invention une tige de palpage 21 qui s'étend sensiblement dans un plan parallèle au plan défini par les directions longitudinale et transversale. Cette tige de palpage 21 est fixée sur une barre 22 pivotant autour d'un pivot 23 dont l'axe de pivotement est parallèle au plan défini par les directions de déplacement longitudinal et transversal du copieur. La tige de palpage 21 agit par l'intermédiaire de la barre 22 et d'un poussoir 24 sur une vanne 25 commandant les déplacements des chariots longitudinal 4 et transversal 11 du copieur, cette vanne 25 commandant en fait l'admission et l'évacuation du fluide d'actionnement dans les chambres des vérins 7 et 16.According to the invention, the template 1 used with this two-dimensional copier consists of a solid of revolution which is held between two tips 20, stationary relative to the chassis 5 of the machine. The feeler device 2 comprises according to the invention a feeler rod 21 which extends substantially in a plane parallel to the plane defined by the longitudinal and transverse directions. This feeler rod 21 is fixed to a bar 22 pivoting around a pivot 23 whose pivot axis is parallel to the plane defined by the directions of longitudinal and transverse movement of the copier. The feeler rod 21 acts by means of the bar 22 and a pusher 24 on a valve 25 controlling the movements of the longitudinal 4 and transverse carriages 11 of the copier, this valve 25 in fact controlling admission and evacuation actuating fluid in the chambers of the jacks 7 and 16.

Afin de pouvoir reproduire un gabarit présentant des gradins verticaux, de sens opposés, tels que 26 et 27, on a prévu, suivant l'invention, d'effectuer une première passe de copiage en parcourant le gabarit dans un premier sens avec une première orientation de la tige de palpage (figure 1), cette première passe permettant de réaliser les gradins tels que 26, de modifier l'orientation de la tige de palpage à la fin de cette première passe, et d'effectuer une seconde passe en sens opposé à la première avec une seconde orientation de la tige de palpage (figure 2), cette seconde passe permettant de réaliser des gradins tels que 27.In order to be able to reproduce a template having vertical steps, in opposite directions, such as 26 and 27, provision has been made, according to the invention, for making a first copying pass by traversing the template in a first direction with a first orientation. of the feeler rod (Figure 1), this first pass to achieve steps such as 26, to modify the orientation of the feeler rod at the end of this first pass, and to make a second pass in the opposite direction to the first with a second orientation of the feeler rod (Figure 2) , this second pass allows for steps such as 27.

Suivant un premier exemple de réalisation de l'invention, représenté sur les figures 1 à 4, on modifie l'orientation de la tige de palpage en faisant pivoter l'ensemble de la vanne de commande 25, du poussoir 24, du pivot 23, de la barre 22 et de la tige de palpage 21 autour d'un second pivot 28 dont l'axe de pivotement est perpendiculaire au plan défini par les directions longitudinale et transversale. Le pivotement de cet ensemble est commandé par un vérin ou groupe cylindre-piston 29 s'étendant en direction longitudinale, dont le cylindre 30 est fixé à une pièce de support de vanne 31et dont le piston 32 est relié au corps de la vanne 25 par l'intermédiaire d'un pivot 33 d'axe perpendiculaire au plan défini par les directions longitudinale et transversale et d'une glissière 34 fixée au pivot 33 et coulissant dans une rainure correspondante pratiquée dans le corps de la vanne 25.According to a first exemplary embodiment of the invention, shown in FIGS. 1 to 4, the orientation of the feeler rod is modified by pivoting the assembly of the control valve 25, of the pusher 24, of the pivot 23, of the bar 22 and of the feeler rod 21 around a second pivot 28 whose pivot axis is perpendicular to the plane defined by the longitudinal and transverse directions. The pivoting of this assembly is controlled by a cylinder or piston-cylinder group 29 extending in the longitudinal direction, the cylinder 30 of which is fixed to a valve support part 31 and the piston 32 of which is connected to the valve body 25 by by means of a pivot 33 with an axis perpendicular to the plane defined by the longitudinal and transverse directions and a slide 34 fixed to the pivot 33 and sliding in a corresponding groove made in the body of the valve 25.

Afin d'assurer un guidage précis de l'ensemble de la vanne, du poussoir, du pivot, de la barre et de la tige de palpage, on a également prévu une rainure 35 concentrique à l'axe du pivot 28 et réalisée dans la pièce de support 31 de la vanne. Un prolongement du corps de la vanne coulisse dans cette rainure 35 de manière à guider la vanne 25 au cours du changement d'orientation de la tige de palpage 21.In order to ensure precise guidance of the assembly of the valve, the tappet, the pivot, the bar and the feeler rod, a groove 35 is also provided concentric with the axis of the pivot 28 and produced in the support piece 31 of the valve. An extension of the valve body slides in this groove 35 so as to guide the valve 25 during the change of orientation of the feeler rod 21.

La pièce 31 de support de vanne peut coulisser en direction transversale sur une pièce 52 solidaire du chariot transversal 11. Cette possibilité est utilisée pour ajuster la position de la tige de palpage 21 par rapport au gabarit 1 avant le début des opérations de copiage, ce support 31 restant immobile par rapport à la pièce en U 13 du chariot transversal 11 au cours des opérations de copiage proprement dites.The valve support part 31 can slide in a transverse direction on a part 52 integral with the transverse carriage 11. This possibility is used to adjust the position of the feeler rod 21 relative to the gauge 1 before the start of the copying operations, this support 31 remaining stationary relative to the U-shaped part 13 of the transverse carriage 11 during the actual copying operations.

On a illustré sur la figure 5 un autre exemple de réalisation du dispositif de palpage 2 permettant, suivant l'invention, de donner à la tige de palpage du gabarit deux orientations différentes. Dans ce cas, la barre 36 du dispositif de palpage porte deux tiges 37 et 38. Chacune de ces tiges peut être utilisée comme tige de palpage lorsqu'elle se trouve en position sur le gabarit 1. Ces deux tiges 37 et 38 sont sensiblement parallèles et s'étendent d'un même côté par rapport à la barre 36. Cette dernière est reliée à l'arbre 39 d'un moteur rotatif 40, notamment un moteur électrique, par l'intermédiaire d'un pivot 41 dont l'axe de pivotement est situé exactement au milieu entre les deux tiges et est parallèle au plan défini par les directions longitudinale et transversale lorsque le dispositif palpe un gabarit.Another example is illustrated in FIG. 5. ple embodiment of the feeler device 2 for, according to the invention, to give the feeler rod of the template two different orientations. In this case, the bar 36 of the probing device carries two rods 37 and 38. Each of these rods can be used as a probing rod when it is in position on the template 1. These two rods 37 and 38 are substantially parallel and extend on the same side with respect to the bar 36. The latter is connected to the shaft 39 of a rotary motor 40, in particular an electric motor, by means of a pivot 41 whose axis pivot is located exactly in the middle between the two rods and is parallel to the plane defined by the longitudinal and transverse directions when the device palpates a template.

L'arbre 39 du moteur 40 est sensiblement parallèle à la direction transversale, de telle sorte que lorsqu'on désire modifier l'orientation de la tige de palpage, il suffit de changer de tige en faisant tourner la barre 36 de 180° autour de l'arbre 39. Cette barre coopère avec un poussoir 24 qui agit sur une vanne de commande 25, comme dans l'exemple de réalisation suivant les figures 1 à 4.The shaft 39 of the motor 40 is substantially parallel to the transverse direction, so that when it is desired to modify the orientation of the feeler rod, it suffices to change the rod by rotating the bar 36 180 ° around the shaft 39. This bar cooperates with a pusher 24 which acts on a control valve 25, as in the exemplary embodiment according to FIGS. 1 to 4.

La pièce à usiner est portée par un mandrin 42 d'un tour qui la maintient en rotation à une vitesse appropriée, autour d'un axe parallèle à l'axe longitudinal. La tourelle porte-outil 15 suit fidèlement les déplacements de la tige de palpage 21 grâce à un dispositif hydraulique comprenant notamment la vanne de commande 25, les vérins 7 et 16 et une source de fluide hydraulique sous pression (non représentée). Les conduites 43 et 44 relient la vanne aux chambres du vérin longitudinal 7. Les conduites 45 et 46 relient la vanne aux chambres du vérin transversal 16 et les conduites 47 et 48 servent à l'amenée du fluide hydraulique sous pression et au retour de ce fluide.The workpiece is carried by a mandrel 42 of a turn which keeps it in rotation at an appropriate speed, around an axis parallel to the longitudinal axis. The tool-holder turret 15 faithfully follows the movements of the feeler rod 21 thanks to a hydraulic device comprising in particular the control valve 25, the jacks 7 and 16 and a source of hydraulic fluid under pressure (not shown). The lines 43 and 44 connect the valve to the chambers of the longitudinal cylinder 7. The lines 45 and 46 connect the valve to the chambers of the transverse cylinder 16 and the lines 47 and 48 are used for supplying the hydraulic fluid under pressure and for returning it fluid.

Etant donné qu'on a prévu d'effectuer deux passes de sens opposés sur le gabarit 1 et donc sur la pièce à usiner 3, la tourelle 15 porte deux outils 49 et 50, le premier outil 49 est utilisé pour usiner la pièce 3 dans le sens de la flèche 6 (figure 1) et le second outil 50 est utilisé pour usiner la pièce 3 dans le sens opposé à la flèche 6 (figure 2). Afin de pouvoir changer d'outil, la tourelle porte-outil 15 peut être amenée à pivoter de 180° par des moyens qui agissent en même temps qu'on modifie l'orientation de la tige de palpage 21, ces moyens étant notamment constitués par un moteur électrique 51.Since it has been planned to make two passes of opposite directions on the template 1 and therefore on the workpiece 3, the turret 15 carries two tools 49 and 50, the first tool 49 is used to machine the workpiece 3 in the direction of arrow 6 (Figure 1) and the second tool 50 is used to machine the part 3 in the opposite direction to the arrow che 6 (figure 2). In order to be able to change the tool, the tool-holder turret 15 can be made to pivot 180 ° by means which act at the same time as the orientation of the feeler rod 21 is modified, these means being in particular constituted by an electric motor 51.

Il doit être entendu que la présente invention n'est en aucune façon limitée aux formes de réalisation ci-dessus et que bien des modifications peuvent y être apportées sans sortir du cadre du présent brevet.It should be understood that the present invention is in no way limited to the above embodiments and that many modifications can be made thereto without departing from the scope of this patent.
